Just wanted to update (very late in coming) that Vertigo no longer uses any gelatin clarifiers in any of their beers. This has been true for quite some time and there is no chance that any beer in the market contains this ingredient.

"Unfortunately we currently do use gelatin as a clarifier in most of our beers. Our Razz Wheat and soon to be hefeweizen do not use any of those ingredients."
